The cruise industry is a powerhouse in global tourism, generating billions of dollars annually and serving millions of passengers worldwide. As this sector continues to grow, so does the urgency to address its environmental impact. Cruise lines are stepping up by adopting sustainable practices, with a significant focus on reducing waste and preserving marine ecosystems.
A major part of these efforts involves rethinking food packaging. The Cruise Lines International Association (CLIA), a leading voice in the industry, actively promotes policies that support sustainability, safety, and health. Among CLIA member cruise lines, sustainable tourism is a key priority, and eco-friendly food packaging is a critical component of that mission.
Why the focus on packaging? Plastic waste—such as straws, lids, and bags—poses a serious threat to marine life. Floating plastic debris harms wildlife through entanglement and ingestion, disrupting delicate ocean ecosystems. By switching to sustainable food packaging, cruise lines can help protect marine environments and significantly reduce their waste footprint.
In this article, we’ll explore the best sustainable food packaging alternatives for cruise lines, from compostable takeout boxes to biodegradable cutlery. Whether you’re looking to reduce onboard waste or enhance your sustainability efforts, these eco-friendly solutions can make a lasting difference.

Problems with Traditional Plastic Food Packaging
Traditional plastic food packaging presents serious risks to both human health and the environment. Certain types of plastic, such as those containing BPA (Bisphenol A) and phthalates, can leach harmful chemicals into food and beverages. These substances are known to disrupt hormones and have been linked to health concerns like reproductive issues and developmental delays.
On an environmental level, plastic food packaging is a major contributor to the growing problem of ocean plastic pollution. According to the United Nations, this issue has escalated to a “planetary crisis”, with millions of tons of plastic waste, including packaging, accumulating in oceans and harming marine ecosystems. One of the most troubling results of plastic pollution is the creation of microplastics.
What Are Microplastics?
Microplastics are tiny plastic fragments—less than 5 millimeters in size—that form when larger plastic items like straws, bags, and containers degrade. These particles are incredibly durable and widespread, polluting oceans, rivers, soil, and even the air.
Marine organisms, from plankton to large fish, often consume microplastics, mistaking them for food. This introduces plastic particles into the food chain, which can eventually affect human health when people consume seafood contaminated with microplastics. If current trends continue, researchers predict that by 2050, there could be more plastic in the ocean than fish, making the reduction of plastic waste more urgent than ever.
Examples of Food Packaging Types That Lead to Ocean Pollution:
1. Plastic Straws
Plastic straws are a prime example of non-biodegradable waste with a significant environmental impact. Plastic straws can take up to 1,000 years to decompose, and during that time, they often end up in waterways, where they pose a threat to marine life. Sea turtles, dolphins, and other marine species can suffer from injuries, entanglement, or death after coming into contact with discarded plastic straws.
2. Plastic Bags
Plastic bags are another harmful form of food packaging. They start as fossil fuels and often end up polluting the ocean. Shredded plastic bags are frequently mistaken for food, such as jellyfish, by marine species like sea turtles. Ingesting plastic bags can cause intestinal blockages, malnutrition, and often leads to death. Additionally, fish and other sea creatures consume micro-fragments of plastic bags, transferring harmful particles through the food chain to larger predators, including humans.
Benefits of Choosing Sustainable Food Packaging on Cruise Ships
